ECM Harness Connector

Terminals

The Electronic Control Module (ECM) uses four

connectors that have 24 terminals to interface to the

wiring harness.

The Injector Driver Module (IDM) uses two

connectors that have 24 terminals and one connector

that has 32 terminals to interface to the wiring

harness.

Programming Parameters

Programming Parameters

7. Turn the ignition keyswitch to the ON position and

the OFF position when instructed to ensure that

the flash file is saved.

8. Only disconnect the 27610401  CA3

Communication Adaptor Kit from the ECM when

the  “Successfully Programmed”  message

appears.

Programming Parameters

The electronic service tool can be used to view

certain parameters that can affect the operation of the

engine. The electronic service tool can also be used

to change certain parameters. The parameters are

stored in the Electronic Control Module (ECM).

Flash Programming

Flash Programming – A method of loading a flash

file into the Electronic Control Module (ECM) and the

Injector Driver Module (IDM)

Flash Programming a Flash File

1. Contact “PartsHelpdesk@Perkins.com ” in order to

obtain the correct flash file. The flash file will be

sent via e-mail.

2. Use a 27610404 Power-Up Harness to provide

power to the ECM during the flash programming

procedure.

Note: If the 27610404 Power-Up Harness is not

available, the ECM and IDM must be correctly

connected to the batteries. The ECM must be able to

control the main power relay and there must be a

switch on the supply to ECM pin X3:3 and IDM pin

X3:9. The main power to each module must be via

relays that are switched by the modules. Refer to

Troubleshooting, “Engine Wiring Information”.

3. Connect the ECM to the computer using the

27610401 CA3 Communication Adaptor Kit.

Refer to Troubleshooting, “Electronic Service

Tools” for more information.

4. Start the flash file program that was sent via e-mail.

Note: The flash file is a self-contained executable file.

No other software is required other than the CA3

Communication Adaptor drivers that are included with

the  27610401 CA3 Communication Adaptor Kit.

5. Select the “Perkins CA3”  from the “Cables”   drop-

down box.

6. Follow the on-screen instructions in order to install

the flash file.
